Difference Between Fan and Blower

Today we will learn about difference between fan and blower. The fan and blower are two different kind of machines belong
to the same group. Both these machines are used to flow a gas or mostly air in a
large area but the main difference between fan and blower is that the fan is
operate at low pressure while blower is operate at high pressure. These machines are used in many industrial
machines for air conditioning or cooling purpose.

The fan consist a rotor witch is equipped with some blades.
This rotor is rotate by a electric motor or sometimes by a mechanical machine.
It is primary used to flow the air into a large space. Mostly fans used to blow
the air axially or the direction of the air flow along the axis of the rotor. Fans
blow large volume of air with minor change in pressure. It has specific pressure
ratio is 1.1.

Blower is different from fan. It is a centrifugal unit which
blows the air radially. It consist a impeller equipped with series of blades which
are designed to flow air radially. It blow the air or gas with a moderate pressure
change. The change in specific pressure ratio is 1.11 to 1.2.

Difference between fan and blower:

S.No.

Fan

Blower

1.

The pressure change in fan is about 1.1

The change in pressure in blower is about 1.1 to 1.2

2.

It is used to flow of gas or air in open space.

It is mostly used to flow of gas in specific direction.

3.

It blows gases or air in every direction.

Blower is used to point the air in specific direction.

4.

It is smaller than blower.

Blowers are mostly larger than fan

5.

It consumes less energy.

It consist more energy.

6.

It does not have moving blades.

It may have moving blades to pointed air in specific
direction.
